Rating: 5/5 Easy thx video instructions January 5, 2017 I received this product as part of upgrading my 2010 MacBook Pro. I received all my items within a couple of weeks as it had to cross the border. Duty was about $55, but even with the exchange and duties it was still a better deal than through Amazon.ca.

The installation video was very helpful. I used another computer to follow with the video. This company has been highly recommended by others who are very involved with computing, relying on them for performance. I'm very happy to have found this company as recommended by others and won't hesitate to do the same. This really helps make my investment in a Mac Product worthwhile for years to come.

Rating: 5/5 Brilliant! December 12, 2016 I've been working with Creative Cloud, Office etc on a Mac Mini mid 2010 for just over a year and the speed has been painfully slow. I'd read on the Apple site that unfortunately the RAM could not be upgraded to anymore than 8GB and upgrading to a SSD looked very complicated for this model. I was 'making do' until I saw a press release from MacSales saying they believed that it was possible to upgrade the RAM for this model.

I bought from MacSales since they are a reputable business and I've had trouble in the past with parts from eBay that didn't work. I fitted the RAM very easily and low and behold the upgrade indeed doubled the speed on my machine.

Needless to say, I'm thrilled! This upgrade has saved me the money I would have spent on a new machine, and the hours spent transferring over all the data / license keys / setting it up.

It has been brilliant, I don't often post reviews but I wanted to in case anyone has any reservations about it working, in light of Apple's advice. It definitely can be upgraded and very noticeably speeds the system up. It's as fast as my laptop which has a SSD. Thank you!

Rating: 5/5 Boosted the speed of my white 2010 model MacBook! November 26, 2016 I bought a white MacBook in August 2011, the discontinued model. It came with 2 GB of RAM. In the last 2 years, it became excruciatingly slow. I read on Other World Computing that my model (currently running the Yosemite operating system) could be upgraded to 16 GB. I was skeptical, but WOW! So much faster! I wish I had upgraded long ago. It was a great price and it has extended the life of my white MacBook. Great buy!

Rating: 5/5 Works great November 24, 2016 I installed these on my macbook pro mid 2010 and it works like a charm despite Apple stating 8GB max is supported. Thanks MacSales for the tests proving them wrong. I'm in the UK so the item took a while to arrive and there was a customs charge of £24.

Rating: 5/5 works perfectly and arrived quickly October 27, 2016 This ram is operating perfectly. Never have any worries concerning purchases here for my old macbook. Only thing I would change is, as I'm an overseas resident, the OWC site doesn't seem to offer a conversion to local rate pricing or am I missing something?. Big plus though, is the very cheap delivery charge compared to many US sites.

Rating: 5/5 New life for my MBP October 24, 2016 Bought this kit for my MBP13 mid '10, since the stock 2 GB + 2 GB became annoyingly insufficient for working with many apps and documents simultaneously (though I have to admit that even with memory thrice overloaded it was quite capable for stable work — great work on memory optimization, Apple!). The result is, roughly speaking,— Wow! Coupled with an SSD, this gives a performance boost so great, that you won't think about getting a new device for a long time, not for performance reasons at least.

P.S. Thank you for fast delivery overseas via discount post option. (less than 2 weeks)

Rating: 5/5 Wow! It works! More RAM and I am cookin'! September 29, 2016 After installing El Capitan in April, 2016 I was choking! Spinning ball with everything I did on my MacMini 2010. At the same time our phone company sold us to another. It took four months for me to troubleshoot and discover that I either buy a new MacMini or try boosting the RAM. The phone company was not the bad guy for this one. It has only been a few hours. I can again have more than one application open; I can actually type and have the cursor with me. Thank you OWC!! Hopefully the jump from 2gb to 16gb will keep me in business for another couple of years.

Rating: 5/5 Easiest upgrade ever! September 12, 2016 Twist the cover off the bottom of the Mini, unclip two RAM chips, clip in 2 new RAM chips, replace cover. Power up and say 'Oh, THAT'S how it's supposed to run!'. Instant performance. See my other review on the Data Doubler for how to make your Mac Mini as fast as possible.

Rating: 5/5 Easy and makes a huge difference August 7, 2016 My son has a mid 2010 MacBook Pro and he was complaining that it was so slow he wanted to buy a new computer. I convinced him to let me upgrade it instead, and for under $300 I was able to upgrade his RAM from 4GB to a whopping 16GB, and I replaced his old hard drive with a solid state drive. I also upgraded his OS to El Capitan. He was so excited. Said he felt like he had a new MacBook. Super fast opening MS office apps, and now he can play more games on it. I am sure this extended the life of the computer by several years. The installation videos on this site are awesome, and the ease with which they help you find the right parts for your specific MacBook is really great. I was so happy with the result I did the same upgrades to my 2011 MacBook Pro.

Rating: 5/5 Very Good, Easy Install July 29, 2016 I have installed this type of RAM upgrade on about 4 laptops now. They have all worked well and enable us to recycle older models as backup units. (I.e., enable a more recent operating system to be installed without excessive loss of speed) Often, we also install a OWC SSD drive when the drive shows issues. I have only had one problem where the on 8GB chip on another computer (MacBookPro8,2) did not work, but it was replaced & then worked fine. It's a non lazy, cost effective way to get more out of your expensive hardware.
